WhatsApp Message Fails with "Invalid Parameter" Error

Problem

Your WhatsApp message fails to send and displays an "Invalid Parameter" error.

Why This Happens

WhatsApp doesn't allow you to send messages to the same phone number you're sending from. If your "From" number and "To" number match, you'll see this error every time.

How to Fix It

Step 1: Check your message settings and verify the "From" number (your WhatsApp business number).

Step 2: Check the recipient's phone number in the parent or family profile.

Step 3: If both numbers are identical, update the recipient number to a different phone number.

Pro Tip: If you're testing WhatsApp messages, use a different phone number than your business line. You can't send test messages to yourself through WhatsApp.

Still Having Issues?

If you've confirmed the numbers are different and still see this error, check that both phone numbers include the correct country code and are formatted properly (example: [phone]).
